Presentation

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

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

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