Presentation

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

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

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