Presentation

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

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

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