Presentation

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

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

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