Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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