28 is the sum of the first natural numbers. 1+2+3+4+5+6+7 = 28 28 is the sum of the first primes. 2+3+5+7+11 = 28 28 is the sum of the first non-primes 1+4+6+8+9 = 28 28 is the only known number that can can be expressed as all 3 of the above sums. For example 36 is also the sum of the first natural numbers (1+2+3+4+5+6+7+8), but not a sum of first primes or first non-primes. 10 is the sum of the first primes (2+3+5) and natural numbers (1+2+3+4) but not the first non-primes (1+4+6).

Holy Shit, Batman, 28 is 4 x 7! Accordingly, x/28, whenever x =4n, is the same as n/7 which gets us back to the freaky repeating decimal (0.142857) discussed on the 7th, the 14th and the 21st. The decimal part of n/7 where n is a natural number not a multiple of 999,999 or 7 is the remainder x 0.142857 repeated on out to infinity. n/14 has similar rules, as does n/21, and n/28 which is, for example ...

1/28 = 0.0357142857142857 & repeat 142857 indefinitely 2/28 = 1/14 = 0.07142857142857 & repeat 142857 indefinitely 3/28 = 0.107142857142857 & repeat 142857 indefinitely 4/28 = 1/7 = 0.142857142857 & repeat 142857 indefinitely 5/28 = 0.17857142857 & repeat 142857 indefinitely
