Presentation

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

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

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