Four Letter Sequences (Posted on 2005-01-12) Difficulty: 3 of 5
A sequence of letters is considered "valid" if it occurs as a substring of a common English word. For example, "RGRO" is valid because it occurs in the word "undeRGROund."

Find a sequence of four distinct letters such that all 23 non-identity permutations of the sequence are valid.
