Other Lagrange identities

 * Lagrange's identity as applied to the central binomial coefficient and random walks; no article available. See Brews ohare (talk) 14:32, 24 April 2010 (UTC)


 * Lagrange's lemma or Lagrange's group theorem states that a group G, a subgroup H of G and a subgroup K of H satisfy the relation (G:K)=(G:H)(H:K) connecting the cardinality of the groups and subgroups.. Brews ohare (talk) 13:42, 27 April 2010 (UTC)


 * Lagrange's identity also refers to the relation between the squared volume of of a parallelpiped and the Gram determinant of the vectors defining it. See also HW Eves. Brews ohare (talk) 22:15, 26 May 2010 (UTC)


 * Lagrange's theorem states that the order [h ] of any subgroup of a group G must be a divisor of [g ], the order of G. Brews ohare (talk) 19:01, 31 May 2010 (UTC)

Entries for existing articles only
I've removed the line about "Lagrange's identity as applied to the central binomial coefficient and random walks" as there's no such article. Each entry should have one link only, to the article on the topic or sometimes one mentioning it. If it's not mentioned anywhere then it should not be listed. Also entries should have just enough description so readers can tell which article they want (so no explanation, refs), and should be formatted consistently. See MOS:DAB for details.-- JohnBlackburne wordsdeeds 15:00, 24 April 2010 (UTC)
