Non-normal motif-candidate frequency distributions. Example frequency distributions of the number of copies nS(M) of the candidate motif M found in networks similar to four bacterial transcription factor networks, as approximated by drawing 10,000 comparison networks from each \( \mathbbm{S}(G) \). The actual frequency nG(M) of the candidate motif M in the original network is also shown for comparison
