Prime Gap Rules six n harmony rule visualization
Six n harmony rule = avoid_Prime3_cut rule.
6*n-1 prime cross n line, 6*n+1 prime cross n line in turn.
Prime has 6*n-1 and 6*n+1 two groups. Consecutive prime difference is prime gap.
Let p(k+1)-p(k)=g(k) Except prime 2 and 3, prime gap is always even number.
primeGap%6 has 0, 2, 4 three possible values.
primeGap%6=0 say p(k+1) and p(k) both be 6*n-1 or both be 6*n+1.
primeGap%6=2 say p(k) is 6*n-1 and p(k+1) is 6*n+1 . Example 17+2=19
17=6*3-1 , 19=6*3+1 . Gap 2,8,14,20 etc. must be from 6*n-1 to 6*n+1
primeGap%6=4 say p(k) is 6*n+1 and p(k+1) is 6*m-1 . Example 19+4=23
19=6*3+1 , 23=6*4-1 . Gap 4,10,16,22 etc. must be from 6*n+1 to 6*m-1
primeGap%6=2 gap follow primeGap%6=2 is forbidden.
primeGap%6=4 gap follow primeGap%6=4 is forbidden.
primeGap%6=2 gap follow primeGap%6=4 is allowed.
primeGap%6=4 gap follow primeGap%6=2 is allowed.
Gap 2,2 is not allowed, ONLY initial prime 3,5,7 has gap sequence 2,2 .
Gap 20,12,14 is not allowed, 12%6=0 is transparent, 20%6=2,14%6=2 forbidden.
Prime5 cut rule , include 7,11,13,17,19
Allowed gap sequence may be cut off by composite contain 5,7 etc.
Gap sequence 6,6,6,6 void by multiple of five, 6,6,6,6 never show up.

keep all  or other choice 
(8)23 yes  or not. 
If click [ all ] box, program change to [prime] 
then change to [b:6n-1] to [c:6n+1] to [delPrim]

What is "prime column" ? In next graph 
Bottom prime03 black/yellow row, a black square indicate that column top start a new prime. 03,05,07,11,13 black squares all start a new prime, but 09 yellow square '$' NOT start a new prime. From yellow square '$' move up to top find red square '$' This red square '$' is not prime07 row left most (first) red or blue. (Red square '#' start a new prime07 row) keep prime choice allow reader study the graph pattern. <a name="docA003"> All prime column has black prime3 at bottom. Column top color reveal this red prime 6*n+1 (7,13,19 etc.) or blue 6*n-1 (5,11,17 etc.) property. All color in between are opposite to top color! An interesting observation. All non-prime column has yellow at column bottom and mixed red/blue or all blue or all red. Worth further study. <a name="docA004"> (8)23 yes or not allow reader add extra information to graph or delete it.

Please see under red, yellow, blue graph 106,04,13,11,00 cannon shock there is a white row for x-axis. Main program do not add number to x-axis white row, allow narrow color bricks like emphtme1.jpg show. When LiuHH write hand work insert numbers to x-axis white row. If reader use table code in Box22 and also insert numbers, then it is better write code to do this job. <a name="docA006"> In click [gevmpr00()] create html table code in Box22. click [show Box22 table] in prime_e3.htm display html table. Above two clicks x-axis white row do not have numbers.

Above three clicks output even 06 08 10... in x-axis white row, color bricks become wider. click add [odd] insert odd 03 05 07 09 11... click add [eo] insert even and odd. click add [oe] insert odd and even.

even and primes. That is change 
from  9 , 2,3,4,5,6,7

all work with 6*n-1 or 6*n+1 type primes. 
Start from 5 to infinity. These columns sum 
not include prime 3. Because 3 not fit 6*n±1.

x selection is 1 or 2. In Future prime column sum list 
column 1 is [odd number], column 2 is [even number] .
y selection is 3 or 4 or 5 or 6 or 7 or 8 or 9. In
