Try the Encyclopedia of Integer Sequences.
https://oeis.org/
It found many answers to your question: a sequence of interest for some
reason that begins 1,2,8. In fact, there are 2,210 matches. The
first one that comes up: A000165, the "double factorial (2n)!!", where
0!! = 1, 2!! = 2, 4!!=8. If THAT is your sequence, then the next one is
6!!=48
