Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(5,6,10,11)(7,12,8,9)(13,14,19,25,18,16,17,21)(15,20,26,28,23,22,24,27);(1,2,3,4)(5,7,9,6,10,8,12,11)(13,15,18,23)(14,20,16,22)(17,24,19,26)(21,27,25,28);(2,4)(13,16,18,14)(15,22,23,20)(17,21,19,25)(24,27,26,28);(5,8,9,11,10,7,12,6)(15,23)(20,22)(24,26)(27,28)
