This is the 13,532-nd antisymmetric Dirichlet (136,519-th Dirichlet) eigenfunction in the (unit-edged) regular pentagon. It has about about 250 wavelengths across the pentagon. Its eigenvalue is about $\lambda=1,000,126.718$; which is the 81,917-th distinct Dirichlet eigenvalue. Click on it for a high resolution nodal pattern (20 pixels per wavelength).

I am interested in calculating eigenvalues of the Laplacian for two-dimensional polygons, mostly for the regular pentagon. My project consists of two main parts. One is to calculate very many eigenvalues (over 160,000 of them) and the corresponding eigenfunctions, the other is to calculate very precise eigenvalues (at least 1000 digits).
