2 and 5 cuts out 60% of any ten digit numbers from being prime.......the end digit..............but leave 40%...............................like 40 - 60.............a 20 number span.............centered about 50..which is halfway to 100.........from 0.........zeroes, Dr. Riemann.................

Not only that...........but from 40 - 60.........there are exactly 5 primes..........41, 43, 47, 53, 59....................3 less than 50.............2 above it......................3 and 2.............an inverted..........2, 3.......the start of all primes.............combine that with................15 and 10..............under 50.......there are 15 primes..............10 above it.................for all primes less than 100................15 and 10 factor......by 5................5 * 3 = 15..............5 * 2 = 10.................3 and 2..........fractal patters....................the list of 5 primes.......from 40 - 60.............................20 number span........2 10s...................like 1/2.........................10s..............2 of them..............garbled..........the 5 primes start with 41...........the 13 prime.........a gabled pi.............pi............spin............around a circle................cycles.................fractal patterns...........
