Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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