Chimera is {R,B,NN,Camel,Zebra} getting close in value to Conway's
Angel, who can leap to any square away n=x, x anything you want. Angel n=7 on 8x8 leaps to any other square, covering the whole board. Maximum unobstructed range of centralized Chimera here of Haynie device is not that 63 squares of British mathematician Conway, but 55 squares. Add Antelope 3,4 and Giraffe 1,4. Then super-Chimera is {R,B,NN,Camel,Zebra,Antelope,Giraffe}. Super-Chimera reaches all 63 squares from the four central squares but the radial ones arrived by sliding. Make Rook Buddha and Bishop Rakshasa and Nightrider Grandmaster. Then that hyper-Chimera as all-leaping {Buddha,Rakshasa,Grandmaster,Camel,Zebra,Antelope,Giraffe} encompassess when centralized Conway Angel n=4 (only) including all that one's squares and more, but not Angel n=5 on enlarged boards. How many hyper-Chimeras would defeat single Conway Angel n=19 on 20x20? As few as four or many as twenty, what one number between suffices? If they are all aligned adjacent in line from a corner along one edge, how many moves will it take to spread them out and kill the Angel?
