We complete the Wilf classification of signed patterns of length 5 for both signed permutations and signed involutions. New general equivalences of patterns are given which prove Jaggard's conjectures concerning involutions in the symmetric group avoiding certain patterns of length 5 and 6. In this way, we also complete the Wilf classification of S 5 , S 6 , and S 7 for involutions.doi:10.1090/s0002-9939-08-09492-6 fatcat:6wvgfqo2pzahnnfbyryqcpavoa
