Presentation

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

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

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