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