Presentation

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

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

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