Previously the question concerning edits of 6 characters was asked Editing tags not allowed because not 6 characters?, however the answers provided were not satisfactory for the question. It is often the case that a single sign needs to be changed or a trivial typo disrupts the flow. In addition some edits are made in series as the question/answer are read over.
Specifically I am writing to make a change to the page How does the Higgs mechanism work?. My concern is an edit of lambda squared to lambda in the Lagrangian under the header putting it all together. This matches the quartic interaction as typically written and correspondingly as the potential as defined above.
