Presentation

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

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

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