One answer would be to read John Fox's rather good book, for which car is the corresponding R package.
Another is to look up leven'es test; a reasonably authoritative web reference for the calculation is http://www.itl.nist.gov/div898/handbook/eda/section3/eda35a.htm
if you followed that, you would find that 356 turns up somewhere important ...
A clue: It is unlikely to be coincidence that you have 358 data points in 2 groups.... and that the 356 turns up in the column headed "Df" in the leveneTest output.
