Presentation

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

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

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