[seqfan] A032528: [ 3 n^2 / 2 ] as an cellular automaton.

[Omar E. Pol]

Dear Neil,

It appears that A032528:  [ 3 n^2 / 2 ] is also the number of "ON" cells 
after n-th stage in an 2-dimensional cellular automaton. The illustration of 
initial terms shows a structure which looks like concentric hexagons.

Best regards,

Omar E. Pol
