Presentation

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

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

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