In a Nutshell:
 
The Seed

"The symmetric group S6 of permutations of 6 objects is the only symmetric group with an outer automorphism....

This outer automorphism can be regarded as the seed from which grow about half of the sporadic simple groups...."

-- Noam Elkies, February 2006

This "seed" may be pictured as

within what Burkard Polster has called "the smallest perfect universe"-- PG(3,2), the projective 3-space over the 2-element field.
