(Full name: Judson S. McCranie.) I've contributed and extended several sequences, almost all with computer searches. I have B.S. degrees in math and physics, a master's degree in applied math and a M.S. in computer science (theoretical CS).


  • sequences that grow roughly exponentially
  • number theory functions.


  • decimal digits of constants (generally)
  • sequences that have an arbitrary parameter (generally)
