Presentation

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

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

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