I tried this 4 years ago when SDMB was playing Mornington Crescent, whimsically making a temporary change to the page of an obscure mathematician.
These mathematicians do enjoy their flights of fancy. I’ve no idea whether the analysis was actually correct or not, but the work did specifically assume that stations were configured into a Monster Group topology. (Discussion of this restriction was relegated to the end-notes.) The London Underground will need to expand quite a bit before it has enough stations to populate the Monster Group.
As you can see from his wiki page , Thorold Gosset led the way in solving MC for special topologies. He went undefeated for 219 games (a record which, AFAIK, still stands) during that era when the Underground had exactly 120 stations and was instrumental in the expansion to 240 stations (an expansion which of course overshot to lamentable consequences).
As to the game presently in progress here, I must say some of the gambits and ploys have been quite impressive. There are several of you who would feel quite at home in our Tuesday games at Bethlem Hospital.
But within half an hour the change was flagged “citation needed”; 24 hours later it was gone. I’ve doctored the first URL in the above quote to point to the fake page:
