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