# Talk:Smarandache-Wellin primes

How does a 'Derived S-W number' work when a digit is repeated more than base-1 times? --Nigel Galloway (talk) 17:09, 27 March 2023 (UTC)

They're just concatenated, the first one comes from "2357111317192329313741434753596167717379838997101103107109113127131" -> {4,19,4,12,3,3,2,11,2,7} (4 zeroes, 19 ones, etc) and 4194123321127 is prime. --Petelomax (talk) 18:28, 27 March 2023 (UTC)

## Whellen

The Raku and Phix code refers to Wellin as Whellen. Is that on purpose?--Steenslag (talk) 21:51, 2 April 2023 (UTC)

I think it’s just a mistake. These numbers are named after Mathematica expert, Paul R Wellin, and I’m certain the spelling is correct. --PureFox (talk) 22:15, 2 April 2023 (UTC)
Ah. Indeed. That was a typo that I made in the Raku entry and probably Pete copy-pasted the output verbiage into Phix without spellchecking. (In my rather weak defense, I work with two different people whose last name starts with Whe, so I probably added the extra 'h' by muscle memory.) --Thundergnat (talk) 15:27, 3 April 2023 (UTC)
