Me, 1977, two years before I discovered the Handbook of Integer Sequences in the library

Me, with my old workstations, working for the OEIS

Updated 4/2/24

(Full name: Judson Shasta 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). I live in Rome, Georgia, U.S.

Likes:

• sequences that grow roughly exponentially
• number theory functions.

Dislikes:

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

Contact me:

• E-mail me through OEIS.

• To email me directly, replace the digits in JSM1430@judmccranie.com with the first four prime numbers.

• To write to me, my street address is the fourth odd prime number. The street name is Exxxxxx Oaks Blvd, where Exxxxxx is a word commonly interchanged with "British". The city is above. The prime factors of the zip code are 3, 5, and 2011.
