comment How to express an irrational as a continued fraction in computer with high precision?
Rather than "up to 16 bits" being not quite right, it's totally wrong. Typical IEEE754 64-bit double-precision numbers use effectively 53 bits for mantissa, giving ~ 16 decimal digits accuracy. (15.95... = 53 * ln(2)/ln(10).)

comment Maximizing growth rate in betting on multiple events
Question 1: Suppose $b_{134}$ is the the fraction of stake $s$ that is bet on $\{1,3,4\}$. Suppose $t=b_{134}*s/3$. If events 1 and 3 win and event 4 loses, is the payoff equal to $(1+c_1+1+c_3)*t$ (that is, the amount $s*b_i$ spreads evenly across the elements of bet #$i$) or is it some other value? Question 2: Do all events in a set have to win to get a payoff? Question 3: Since all bets are simultaneous, there appears to be no "long run" to be concerned about, and no reason to act other than Charles suggested in his answer, right?.

comment Maximizing growth rate in betting on multiple events
Ok, let an $i$ be given. What events are elements of bet #$i$ ? Is the amount $b_i$ spread evenly across the elements of bet #$i$ ? Does bet #$i$ get paid off and its result reported to you before you make bet #$i+1$?

comment Maximizing growth rate in betting on multiple events
Is one allowed to bet on the same alternative multiple times? Is the order of bet payoffs specified? Is $b_i$ an amount bet on event $i$, or on some subset of the events?

comment Conditions on polygon to ensure equal interior angles or opposite sides
Yes, the negation of (c) is (c'), "not all opposite sides have equal lengths". Your comment re "if opposite sides are parallel then opposite angles are equal" becomes obviously true via another comment's suggestion to "draw the diagonal" (i.e. call upon Euclid's Proposition 29, "A straight line falling on parallel straight lines makes alternate angles equal to one another...").
