Presentation

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

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

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