Presentation

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

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

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