Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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