Let the rows of a Pascal’s triangle be represented by “ n “ and the columns of a Pascal’s triangle be represented by “ k “. So, the formula to find the entry of an element in the nth row and kth column of a pascal’s triangle is given by – ( n k ) = ( n-1 k-1...
aWe wish to present a simple combinatorial proof of a determinant formula connecting the Catalan numbers and a matrix derived from Pascal's triangle. We prove the formula by counting perfect matchings in a suitably chosen class of graphs. Although the proof relies on results and techniques from ...
