My edit at 198 Hello you asked Oleg Alexandrov to comment about my recent edit at 198 number You could have asked me directly as I m glad to explain my reasoning I removed the facts that 198 100 90 8 and that 198 is a 67 gonal number because I think they are uninteresting I think that is clear for the first fact and the second fact follows from the general rule that 3n is an n 1 gonal number so you can say something like that for every multiple of 3
