Presentation

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

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

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