Baksalary and Baksalary [J.K. Baksalary, O.M. Baksalary, Nonsingularity of linear combinations of idempotent matrices, Linear Algebra Appl. 388 (2004) 25-29] proved that the nonsingularity of P 1 + P 2 , where P 1 and P 2 are idempotent matrices, is equivalent to the nonsingularity of any linear com
