COMMENTS
| These values are important in Diophantine approximation theory and in the geometry of numbers. Krass (1985) proved that the n-dimensional simultaneous Diophantine approximation constant, gamma_n, must satisfy gamma_n >= (16/9)^floor(n/4) / sqrt(a_(n+1)). See web site for a continuation of probable values.
