Incidence Matrix input (need to figure out if it's hamiltionian/eulerian)

Questions
1

Hello. I am trying to input for example 6x6 matrix filled with 0 and 1. I’ve read all the articles like IncidenceGraph—Wolfram Documentation

Also, I tried with IncidenceGraph[{{0, 1, 1}, {1, 0, 1}, {1, 1, 0}}] but it just redirects.

Is there any method to input this kind of graph and figure out if it’s eulerian/half-eulerian/hamilton or planar?

Thank you!

Are you talking about Mathematica? Or are you talking about Wolfram|Alpha?

IndicdenceGraph is a function for Mathematica. So it doesn’t necessarily work in Wolfram|Alpha. Please see the example pages for information on how to do graph theory with Wolfram|Alpha:
