Artist Notes:
|
Considered the most mathematically 'perfect' day because the month and day are perfect numbers - a positive integer that equals the sum of its proper divisors (excluding the number itself). Eg, 1+2+3=6 and 1+2+4+7+14=28. The next triply perfect day (where the year is also a perfect number) is June 28, 8128.
