Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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