Can you stump the Encyclopedia of Integer Sequences?
Every identifiable sequence known to man, including:
Name: Busy Beaver problem: maximal number of steps that an n-state Turing machine can make on an initially blank tape before eventually halting.
Comment: The sequence grows faster than any computable function of n, and so is non-computable.
If your sequence does not appear there, you might want to try the Super Seeker
