Presentation

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

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

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