A094824 Maximum number of longest common substrings of two binary sequences of length n. 4

%I #7 Apr 17 2019 05:52:12

%S 1,2,2,2,3,3,4,6,6,7,7,8,8,10,11,12,14

%N Maximum number of longest common substrings of two binary sequences of length n.

%C A substring of a string is a subsequence of contiguous symbols in the string. For example, 00 is a substring of 001 but not of 010. For this sequence we do not count the multiplicity of occurrence of common substrings.

%H Sean A. Irvine, <a href="https://github.com/archmageirvine/joeis/blob/master/src/irvine/oeis/a094/A094824.java">Java program</a> (github)

%e a(7) = 4 since the two strings 0001011 and 0011010 have as maximum length common substrings the 4 strings 011,001,101,010 and computer search shows that no other pair of strings of length 7 has more than 4 common maximum length substrings.

%Y See A094837 for a related sequence.

%K hard,more,nonn,nice
