What goes around comes around. Which is more Elegant formalization below?
More generalizable, or uplifting, or just clearer? And where is the attribution? Invented in 1970's, Conway's Angel leaps to any square reachable by n King moves. With n = 7, Angel covers 8x8 board; a specific square(4,6) is one at opposite corner of '4,6 rectangle' -- Charles Gilman's 'Gimel'. Thus, CVPage, ever recycling known quantities, by Gilman's 'From Ungulates Outward' transposes problem-theme Classic Angel into following (including non-pre-established names): 12 Wazir, 22 Ferz, 13 Dabbabah, 23 Knight, 33 Alfil, 13 Trebouchet, 24 Camel, 34 Zebra, 25 Giraffe, 35 Satyr, 45 Antelope, 46 Gimel, 56 Rector, 27 Flamingo, 67 Parson, 44 Tripper, 55 Commuter, 66 Quitter, 14 Cobbler, 15 Quibbler; also unnamed 16, 26, 36, 17, 37, 47, 57, 77.
