Hippogonal
A hippogonal chess move is one similar to a knight's move. That is, a leap m squares in one of the orthogonal directions, and n squares in the other, for integer values of m and n. It need not be a 2:1 ratio for m and n. A specific type of hippogonal move can be written , usually with the smaller number first.
For example, the knight itself moves two squares in one orthogonal direction and one in the other—it moves hippogonally. It is a hippogonal mover, sometimes referred to as a leaper.
Other hippogonally moving pieces include the camel, a fairy chess piece, which moves three squares in one direction and one in the other, and thus is a hippogonal mover.
