>Perfect number (1+2+4+7+14=28)
>Triangular number, being the sum of the first 7 positive integers (1+2+3+4+5+6+7=28)
>7, which it also has as a divisor, being considered to symbolise luck and perfection
>Keith number (2, 8, 10, 28)
>the only known number which can be expressed as a sum of the first non negative integers (1 + 2 + 3 + 4 + 5 + 6 + 7), a sum of the first primes (2 + 3 + 5 + 7 + 11) and a sum of the first non primes (1 + 4 + 6 + 8 + 9) and there is probably no other number with this property
>number of Hebrew letters in Genesis 1:1
Is this number the key to all the mysteries of the universe?
