(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A160728 Toothpick cube: a(n) = A160408(n)*6. 1
0, 6, 12, 24, 48, 72, 96, 120, 144, 192, 288, 384, 432, 456, 480, 528 (list; graph; refs; listen; history; text; internal format)



Also, 6 times the toothpick pyramid A160408.

The sequence gives the number of toothpicks after n rounds. A160729 (the first differences) gives the number added at the n-th round.

See also the entry A139250 for more information about the toothpick sequences.
