Here is an online version of Marty and my newspaper article about the possible positions of one remaining peg when playing peg solitaire on various boards https://www.qedcat.com/archive_cleane... Marty and my new book "Putting two and two together" https://bookstore.ams.org/mbk-141/ Martin Aigner's paper "Moving into the desert with Fibonacci". Bit of a pain to access it for free, possible though via this site. https://www.jstor.org/stable/2691046 This paper contains the proof that I am focussing on in this video. It also has Conway's golden ratio based proof. An implementation of the solitaire army game by Mark Bensilum. Use it to play solitaire army general. Note that this implementation starts with all of the bottom squares occupied by pegs. Please read carefully how you are supposed to play the game using this app :) https://www.cleverlearning.co.uk/blog... The paper "The minimum size required of a solitaire army" by George I. Bell, Daniel S. Hirschberg, Pablo Guerrero-Garcia considers all sorts of variations of the basic solitaire army game. The animation and challenge at the end of the video is based on some of the findings in this paper. Highly recommended. https://arxiv.org/pdf/math/0612612.pdf Reaching row 5 in Solitaire Army using infinitely many pegs (featuring a pretty spectacular animation at the bottom of the page) by Simon Tatham and Gareth Taylor https://www.chiark.greenend.org.uk/~s...
