A number has this property if every digit and string of digits appears with expected frequency in its decimal expansion.
A surface is called a this developable of a curve y if it can be parametrized as x(u, v) = y(u)+vA(u), where A is a vector that also has this property. A squareintegrable function φ has this property if it ful lls the condition φ(t) dt = 1. Given a matrix equation Ax = b, the corresponding equation with this property is   AT Ax = AT b, and in this equation, AT A is a matrix with this property. ForasubgroupH ofagroupG,ifxHx−1 =H forallxinH,thenH hasthis property. A number has this property if every digit and string of digits appears with expected frequency in its decimal expansion. For ten points, identify this property, which is possessed by a vector perpendicular to a plane.
