## Teaser 2884: Farewell

**From The Sunday Times, 31st December 2017** [link]

Today I am retiring after editing this column for 40 very pleasurable years. My heartfelt thanks go out to all the setters and solvers of puzzles with whom I have corresponded.

To celebrate the 40 years I threw a party for the puzzle-setters. At the party we assigned a different whole number from 1 to 26 to each letter of the alphabet; for example, we had A=13 and Z=3. We did this in such a way that, for each person present (including me), the values of the letters of their Christian name added to 40.

Bob, Graham, Hugh, Nick and Richard were there, as were two of Andrew, Angela, Danny, Des, Ian, John, Mike, Peter, Robin, Steve and Tom.

Which two?

Victor Bryant also contributed many **Enigma** puzzles for *New Scientist* under the pseudonym Susan Denham.

on19 August 2019 Permalink |I treated this puzzle as a pair of linked alphametic problems in base 27 (so the symbols have values from 1 to 26), using the [[

`SubstitutedExpression()`

]] solver from theenigma.pylibrary. It’s not especially quick, but it is moderately succinct. It runs in 2.60s.Run:[ @repl.it ]Solution:DES and MIKE also add up to 40.There are four ways the letters can be assigned to make the required set of names add up to 40.

The following letters are fixed:

Then C, I, K, N, T, V have one of the following assignments:

The remaining letters: J, L, P, W, Y (and the unused letters: F, Q, X) take on the remaining values: 17, 19, 20, 21, 22, 23, 24, 26 (in any order).

I found multiple solutions, all with MIKE and DES adding up to 40.

I noticed the names which seemed to vary most in value were ANGELA, JOHN and PETER.
