Vi la siguiente foto en la Olimpiada de Matemáticas de Puerto Rico. La figura es una alfombra desplegada.
No pude hacer la parte del cilindro, no introducir símbolos en cuadrados negros.

También puedes usar una matriz para simplificar el código.

Debo admitir que mi "cilindro" no parece muy realista, pero en cualquier caso, el resultado se puede lograr con un código mucho más corto. Si no entiendes algo, no dudes en preguntar, pero creo que escribirmuchoLa recopilación de \node
definiciones se vuelve tediosa.
Dejé su lista de paquetes como estaba porque no sé si los usa en algún otro lugar de su documento, pero muchos de estos no son necesarios para este código.
