### Context When calculating scattering amplitudes using a model created with **FeynRules** (involving matrix operations and linear transformations), I followed the standard workflow: 1. Patched the model with `FAPatch` 2....
The programs automatically quit when running findMappings in FCLoopFindTopologyMappings. My programs are as follows. 4, Hold[Pair][Momentum[k1, D], Momentum[k1, D]] -> 0, Hold[Pair][Momentum[k1, D], Momentum[P, D]] -> 2}, {}], FCTopology[ "qtopo10",...
