## Abstract A class of constraint preconditioners for solving twoโ€byโ€two block linear equations with the (1,2)โ€block being the transpose of the (2,1)โ€block and the (2,2)โ€block being zero was investigated in a recent paper of Cao (__Numer. Math.__ 2006; **103**:47โ€“61). In this short note, we extend
