Numeri con simmetria rotazionale
Dato un numero intero, genera un valore di verità se è lo stesso sottosopra (ruotato di 180 °) o un valore di falsa in caso contrario. 0, 1e 8hanno simmetria rotazionale. 6diventa 9e viceversa. Sequenza di numeri che producono risultati veritieri: OEIS A000787 0, 1, 8, 11, 69, 88, 96, …
