Presentation

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

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

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