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