Feynman periods in phi4-theory

Numerical values for periods in phi4-theory in 4 dimensions.
The dataset contains all periods up to 13 loops, and non-complete samples up to 18 loops.
Numerical approximates for the Hepp bound are included for all graphs. Depending on the loop order, additional properties such as Martin invariants or counts of cuts and cycles are contained.
This data set can be used as a reference for future computations of Feynman periods, as input for further statistical examinations, or as a test case for new algorithms to predict periods.
