AMT/D/19

Puzzle and solution sent to Rolf Noskwith. The text is not written as a letter (nor signed) but rather as a quick-and-dirty explanation of a problem in n-dimensional geometry, taking for granted some of the ideas that probably gave rise to the problem.

Rolf Noskwith (1919-2017) worked with AMT in Hut 8 at Bletchley Park during 1941-42. 

The phone number scribbled in the corner on the back (‘Temple Bar 3878’), in Ralph Noskwith’s hand, was the number of the New Theatre in St Martin’s Lane, near Leicester Square (now the Noel Coward Theatre). (Information provided in May 2023 by Jack Copeland)

Provenance: purchased at auction on 29 March 2023. A tranche of Rolf Noskwith's papers was submitted to Bonhams for auction and this page was extracted and sold as one lot, the rest of the tranche being sold as another lot at the same auction.
