117/-! ## Continued Fraction Connection -/
118
119/-- e has a beautiful continued fraction:
120
121 e = 2 + 1/(1 + 1/(2 + 1/(1 + 1/(1 + 1/(4 + 1/(1 + 1/(1 + ...)))))))
122
123 Pattern: [2; 1, 2, 1, 1, 4, 1, 1, 6, 1, 1, 8, ...]
124
125 φ has: [1; 1, 1, 1, 1, ...] (all 1s)
126
127 Both are "simple" continued fractions in some sense. -/
