Presentation

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

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

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