Would 54-0 be enough to end a filibuster?

[Fiendish Thingy]

5. 54 votes isn't enough to end a specific filibuster, but 51 votes IS enough to kill it forever

A specific filibuster needs 60 votes to bring cloture, or end debate and move to a floor vote on a bill. The exception is reconciliation budget bills, which aren’t subject to the filibuster and can pass with a simple majority.

However, the senate majority leader can move to vote to change the rules; that motion can be filibustered, but the leader can overrule (aka the Nuclear Option) and proceed to a floor vote to change the rule, in this case the filibuster rule. If the rule change gets a simple majority, it stands.
