Did You Know
In mathematics, an Euler brick, named after Leonhard Euler, is a rectangular cuboid whose edges and
face diagonals all have integer lengths. A primitive Euler brick is an Euler brick whose edge lengths are relatively prime.
The smallest Euler brick, discovered by Paul Halcke in 1719, has edges (a, b, c) = (44, 117, 240)and face diagonals (d, e, f ) = (125, 244, , 267).
