Dedicating the beauty of 2020 to Hal Finney:
2020 is a beautiful number because:
o 2020 = 2^2 * 5 * 101
o 2020 = 16^2 + 42^2
o 2020 = 24^2 + 38^2
o 2020 = 2^11 - 28
o 2020 = 10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 [Acknowledgement: Mikko / Finland]
o 2020 = (1 + 1) × (11111 − 1)/11 [Ack/start: Prof Taneja]
o 2020 = 2 × (2 × (222 + 22) − 2)
o 2020 = 3 + (3 + 3) × (333 + 3) + 3/3
o 2020 = 4 + (4 + 4) × (44 − 4)
o 2020 = 55 + 55 × (5 − 5 × 5) − 5
o 2020 = (6 − 6/6 )× ((6 + 6)/6 + 6 × 66 + 6)
o 2020 = 77/7 + 7 × (7 × (7 × 7 − 7) − 7)
o 2020 = (8 × (8 × 8 × 8 −
+ × 8/(8 +
o 2020 = (9 + 9) × (99/9 + 999)/9 = 2020 [Ack/end: Prof Taneja]
o 2020 = ((10 x 9 x 8 x 7 x6)/5+(4 x 3))/(2+1) [Ack: Chris & Colin)
o Q(-2020^0.5) = 8 [relating to ring of integers]

Blessed and Happy New Year to all!
