Presentation

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

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

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