Previous 94×94 {-1, +1} matrix of largest known determinant

|Det R| = 3088283198698664739250235405609677239488239408465248473868926976×293 = 2446×293

Ratio of |Det R| to Ehlich/Wojtas bound: 0.0761647


M'=R RT:



  1. This determinant has been surpassed by a new record.
  2. Cannot achieve Ehlich/Wojtas bound since 93=94-1 is not the sum of two squares.
  3. This form has not been proved to be optimal.
  4. This lower bound was reported by Koukouvinos, Mitrouli and Seberry [KMS].
