Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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